SIX WEEKS. SIX VICTIMS. NO CLUES.

''One down, five to go.''

When a leading psychiatrist is found murdered by insulin injection in his home, with a note bearing this threat, Detective Inspector Paolo Sterling and his team find themselves in a race against time to stop a killer from striking again. But with so little to go on, trying to find the next victim is like trying to find a needle in a haystack.

As the body count rises, and the investigation reaches its critical point, Paolo and his team grapple with what could be their most complex case to date. But just when they think the game is up, they make a shocking discovery that leads them close to home.

With so much at stake, can DI Sterling uncover the truth before it''s too late? Or will those closest to him pay the price?
